Question

How would you use the random sampling method when you are to select a sample of 3 out of 10 students in your class?

Answer 1

The following steps would be involved while using the random sampling technique (lottery method) to select 3 students out of 10 students.

Step1: Write the name of each student on a different piece of paper (total 10 slips). Here, caution must be taken that the slips of paper are identical in all respects (size, colour, etc.).
Step2: Place all the slips in a box or a container and shuffle well.
Step 3: Draw out three slips one by one at random from the box.
Step 4: Students with their name on the drawn slips would be selected as the sample.
